In a small, secluded mountain town, a beloved music festival becomes the epicenter of terror when demonic forces are unleashed upon its unsuspecting attendees. The chaos begins when a malevolent cult awakens an ancient evil that possesses the townspeople, turning them into monstrous creatures. As panic spreads and the body count rises, three unlikely heroes emerge to confront the horrors plaguing their once tranquil community. Kevin, a reserved illustrator struggling with social anxiety, finds himself drawn back to his hometown despite his reluctance to engage with the festival crowd. Accompanied by his friend Jeff, an amiable and easygoing music fan, they reunite with their childhood friend, Natalie, who has returned to her roots as a high school teacher. Together, they must reconcile their past grievances and rekindle their friendship to combat the escalating threat.

Their journey leads them through darkened forests, haunted houses, and eerie streets overtaken by grotesque demons. Time is running out for the trio as the festival-goers are transformed into minions of darkness, prompting them to uncover the source of this supernatural terror. As they piece together clues and face unimaginable horrors, Kevin, Jeff, and Natalie are forced to confront their deepest fears and personal barriers. Bound by a shared purpose and an urgent sense of duty to save their town from complete annihilation, they must rely on their wits, courage, and solidarity. Their quest draws them into a battle that will test their limits and change their lives forever as they strive to restore their town's safety and preserve its spirit from descending into irreversible darkness.
